SD standard deviation
Values with different small superscript in the same row indicate difference at the 5% significance level (parametric tests were applied)
Values with different capital superscript in the same column indicate difference at the 5% significance level (Non parametric tests were applied)
Total sample size per sampling site: N = 180 in Kavoura, N = 180 in Makrigialos, N = 170 in Klidi, N = 60 in Axios estuaries, N = 60 in Gallikos estuaries
Total sample size per season: N = 220 in spring, N = 220 in summer, N = 210 in autumn
